On the possibility of experimental detection of the discreteness of time
Marios Christodoulou, Carlo Rovelli
The Bose-Marletto-Vedral experiment tests a non-relativistic quantum effect due to a gravitational interaction. It has received attention because it may soon be within observationa…
Where was past low-entropy?
Carlo Rovelli
I identify where precisely is low-entropy located in the early universe, arguing that some common answers overplay the role of gravity. I discuss the available interpretations of t…
On the possibility of laboratory evidence for quantum superposition of geometries
Marios Christodoulou, Carlo Rovelli
We analyze the recent proposal of measuring a quantum gravity phenomenon in the lab by entangling two particles gravitationally. We give a generally covariant description of this p…
Physics Needs Philosophy. Philosophy Needs Physics
Carlo Rovelli
Contrary to claims about the irrelevance of philosophy for science, I argue that philosophy has had, and still has, far more influence on physics than is commonly assumed. I mainta…
Small black/white hole stability and dark matter
Carlo Rovelli, Francesca Vidotto
We show that the expected lifetime of white holes formed as remnants of evaporated black holes is consistent with their production at reheating. We give a simple quantum descriptio…
Pre-big-bang black-hole remnants and the past low entropy
Carlo Rovelli, Francesca Vidotto
Dark matter could be composed by black-hole remnants formed before the big-bang era in a bouncing cosmology. This hypothetical scenario has major implications on the issue of the a…
